` Application filed J'ulyv l., 19l. I Serial No. 66,810. (No model.) y

To cir/.ZZ whom it may concern:

Be it known that I, NICOLAS PIEPEa-a subject of the King of Belgium, residing at 18 Rue des Bayards,Liege,Belgium,haveinvented certain new and` useful Improvements in or Relating to Firearms; and I do hereby declare the following to be a full, clear, and ex-V act description of the invention, such as will enable others skilled inthe artA to which itappertains to make and ilse the same.

, which its application is hereinafter described.

The said invention consists, first, in a spe` cialL form of trigger-spring,vand, secondly, in

` a new system of free or sliding extractor' actuated'by the bolt. I

In the accompanying drawings, Figures l, 2, Aand 3 represent longitudinal vertical sections of the action of. a bolt-gun constructed y assume after the gun has been tired, and Fig.

3 showing the same whenfthe breech is opened vby drawing back the bolt. Figs. 4,5, 6, 7, Vand 8 represent var-iousfdetail `parts Vof the lock separately. y i

The same letters of reference indicate corresponding partsin theseveral iiguresof the drawings. y

The spring R, which acts as/"a triggerspring, is in the form of a long flat tongue or blade carrying a heelonsearat R'. VThe rearward extremity ofthe spring-blade is forked and is crossed by a pin T, byfmeans of which it is jointedly connected to the trigger D,V

while its forward end is Vfixed tothe body B of the gun bymeans of'a screw R2, the body portion of the spring occupying a position parallel to and normally lying against the body of the gun. By virtue offthe lifting action of this spring the -sear VR is made to engage with'theshoulder of the cooking-piece C on the `said vcooking-piece, with the` striking-pin P being drawn rearward for cooking thegun', so that on the bolt V being pushed forward to close the breech the sear remains in engagement with the cooking-piece and retains the latter with the striker (to which the body of the gun, so that when the said trigger is drawn rearward it, by reason of the joint connection at T, delico-ts the spring R downward, and thereby disengages the scar from the cooking-piece, which, being thus free, is Vprojected forward with `the striker P by the expansion of the firing-springs, when the parts of'the gun assu me the positions represented inFigtf'Q.

' The extractor E slides freely in a slot or, extending through the lower wall of the gun, and is retained in position in the slot by the spring R, upon the top of which it has a bearing, teeth E F.2 being provided at the opposite extremities of the extractor. The tooth E normally lies in a recess at the breech end' of the barrel B and engages behind the rim of a cartridge, while the other tooth E2 (on the bolt being partially rotated for unlocking it) coincides with a groove V' in the said bolt, and after the bolt hasv been drawn back a certain distance the toothrE2 is engaged by theshoulder at the forward endof the groove, as represented vin Fig. 3, whereupon the extor works freelycither backward or forward` within the ,slot 0o and is supported Vtherein by the spring'R, and'ona cartridge being placed into the chamber of the barrel its rim lies in 15.' The trigger D is shown in elevation in Fig.

6, and the sliding extractor is represented separately in edge view and plan in Figs. 7 and 8. Y

` Having now particularly described and ascertained the nature of my said invention and in what manner the same is .to be performed, I declare that whatI claim is- Y l. In a bolt-gun, 'the combination withthe gun-body having a slot'in'its lower wall, the bolt, and the means for operating the bolt, of the extractor movable in said slot and adapted to be actuated by said bolt, the trigger-spring consisting of a fiat blade arranged IOO 2. In a bolt-gun, the combination with the` gun-body having a slot in its lower wall, the bolt, t'ne striker, and the cocking means, of the trigger-spring consisting of a at blade secured at its forward end to the gun-body and occupying a position parallel thereto and having a sear at its opposite end, the trigger pivoted to said spring, and the extractor movable in said slot and supported therein by the trigger-spring, substantially as described. I5

In testimony whereof I ax my signature in presence of two witnesses.

NICOLAS PIEPER.
